What is this tool?

[Indexmill]

Hi Guys,

I recently bought a box of old stuff and found this item in it. I don't know what this is. It looks like some kind of tool to hold something very small and round.

Any ideas?

Wow. Thank you. There is only that one reference to this tool in all of Googleland. Just wow.

A great reference for little tools is this watch repair catalog. I don’t see yours in there, but that isn’t anything absolute.
